I See Dead People's Books
Legacy Libraries are the libraries of historical people (as well as a few institutions), entered into LibraryThing by dedicated members working from a variety of sources, including published bibliographies, auction catalogs, library holdings, manuscript lists, wills and probate inventories, and personal inspection of extant copies.
